Roxas is a character from Square Enix's video game franchise Kingdom Hearts, who first appears as a cameo during the final scenes of Kingdom Hearts: Chain of Memories and makes his first full appearance in Kingdom Hearts II. He is a "Nobody" who was born from the series' main character Sora after he briefly lost his heart during the events of the first game. Kingdom Hearts II reveals that he is a member of Organization XIII, a group of Nobodies who need him for his ability to wield the Keyblade, a weapon that allows him to capture hearts. As a member of the organization, Roxas bears the title "Key of Destiny" . He is also the protagonist of the video game Kingdom Hearts 358/2 Days, which revolves around his origins. He is voiced by Kōki Uchiyama in Japanese and Jesse McCartney in English.

Kingdom Hearts: Chain of Memories is an action role-playing video game co-developed by Square Enix and Jupiter, and published by Square Enix in collaboration with Disney Interactive in 2004 for the Game Boy Advance. The game serves as an intermediary between the two larger-scale PlayStation 2 games in the Kingdom Hearts series. It was one of the first GBA games to incorporate full motion video (FMV).
